i l:s claims. (c1. 62-129) This invention relates to improvements in aircooling and circulating 'devices and has for its object to provide a newand improved device of this description.

The invention has as a further object to provide an air cooling andcirculating device particularly adapted for cooling rooms. Thevinvention has as a further object to provide an air cooling andcirculating device which is portable and which may easily be moved fromroom to room. The invention has as a further object to'provide an aircooling and circulating device for cooling rooms when one or more of thewindows are open. -The invention has as a further object to provide anair cooling and circulating devicefor rooms, whereby the entirereir'igerating apparatus is in the room and which is provided with meansfor disposing Voi? lthe-heat of the refrigerating apparatus at a pointabove the cooled portion of the room. 'Ihe invention has as a furtherobject to provide a simple, cheap and effective air cooling anticirculating device for cooling rooms in buildings and particularlyadapted for use where it is desirable to have ventilation by means of anopen window. The-invention has other objects which are more particularlypointed out in the accompanying description.

Referring now to the drawing. F13. 1 is a side view of one form ofdeviceembodying the invention,` shown in the room of a building, withparts omitted and broken away;

Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is a plan viewof the device shown in Fig. 2; Fig. 4 is an enlarged cross sectionalview taken on line 4-4 of Fig. 1 and having the central portion brokenaway;` y

Fig. 5 is a sectional view taken on line 5--5 of Fig. 4;

Fig. 6 is an enlarged sec line 6-6 of Fig. 2. l'

vLike numerals refer to like parts throughout the several gures.

ional view taken on Referring now to the drawing, there is illustrated acabinet or case I located in the room. Within this case is contained arefrigerating ap paratus; A cooling element 2, andthere may be one ormoreof them, is located in the cabinet below the upper end thereof andthere is an opening 3 into which the air to be cooled passes. This airbeing then cooled by the cooling element, `passes out of the opening 4into the room so as to cool the room. The cabinet is provided with aconduit or duct 5 which has its upper admission end 5a located on ahigher level than the opening 3. This duct is preferably enlarged at itslower end to provide a chamber 5c and which has a wall 5b, the ductleading to the fan shroud 6. A fan 'I draws the air through this ductinto a chamber 8, which has a wall 8a, and causes the 5 air to pass intocontact with the condenser 9 of the refrigerating apparatus, removingheat therefrom so as to cool the condenser, the warm air passing outthrough the duct or conduit I0, the4 upper end I0a of which is locatedin a higher 10 horizontal plane than the opening 3.

The Ian I is operated by a suitable motor II which may also drive thecompressor I2. There is a liquid line connection I3 between thecompressor andthe condenser and a pipe line I4 from l5 the outlet of thecondenser to the liquid receiver I5. The outlet of the liquid receiver`I5 is connected to the expansion valve I 6, which in turn is connectedby the pipe I'I to the inlet of the` cooling element 2. A pipe I8connects the outlet 20 of the cooling element to the suction inlet ofthe -compressor I2. For controlling the temperature of the coolingelement, there is provided a gas filled bulb I9 connected through thecapillary tube 20 to the expansion. valve I6. A deilector 25 plate 2Iunder the cooling element guides the cold air out through the opening 4and retains any condensation from the cooling element, see Fig. 6.

Any suitable refrigerating apparatus may be used and any suitable meansfor driving it may 30.

also be used, When an-electric motor is used, as illustrated, it may beplugged into any socket in the room and I have illustrated a plug 22connected with the motor and connected to an outlet or socket 23 in thebaseboard.

In this case the window is shown open at the top, the upper sash 24being moved downwardly to secure this opening 26 for the purpose ofventilating the room 25 in which the apparatus is located. Any number ofwindows may be used as 40 desired. I prefer to have the entire apparatusportable and for this purpose I prefer to have it mounted upon Vsomesuitable means for making it-easily portable, as for example the wheels21, so that it can be easily moved to any position in the room and fromroom to room.

I have described in detail a particular construction embodying theinvention, but it is of .course evident that the parts may be variedinmany particulars without .departing from the spirit of the invention asembodied in the claims hereto appendedand I thereforedo not limit myselfto the particular construction shown.

I claim:

1. An air cooling and circulating device comprising a. cabinet locatedin the room to be cooled,

a condenser in the lower part of the cabinet, two

passageways in the cabinet extending from the condenser to the upperpart of the cabinet for conducting air from the upper part of the roomto the condenser and back to theupper part of the room and an evaporatorin the upper part of the cabinet which induces air, from a point belowthe point where the warm air from the condenser is discharged into theroom, to ow over said evaporator by thermosyphonic action, the airflowing over said evaporator being cooled thereby and'discharged intothe lower part of the room, said cooled and discharged air causing thewarmer air in the lower part of the room to rise by thermosyphonicaction and forming a zone of conditioned air below the top ofthecabinet. i

2. An air cooling and circulating device oomprising a cabinet located inthe room to be cooled, a condenser in the lower part of the cabinet, twopassageways in the cabinet extending from the condenser to the upperpart of the cabinet for conducting air from the upper part of the roomto the condenser and back to the upper part of the room and anevaporator in the upper part of the cabinet which induces air, from apoint below the point where air passing to the condenser enters thecabinet and also below the point where the warm air from thecondenser'is discharged into the room, to flow over said evaporator bythermdsyphonic action, the air flowing over said evaporator being cooledthereby and discharged into the lower part of the room, said cooled anddischarged air causing the warmer air in the lower part of the room torise by thermosyphonic action, and forming a zone of conditioned airbelow the top of the cabinet.

3. An air cooling and circulating device comprising a cabinet located inthe room to be cooled, an evaporator in the upper part of the cabinet,said cabinet having an air admission opening for admitting air from theupper part of the room into contact with said evaporator, said cabinethaving a discharge opening through which air cooled by the evaporatorpasses, said evaporator inducing air to ow over it by thermosyphonicaction and out of said cabinet into the lower part of the room anddisplace the warmer air in the lower part of the room without drafts andcause said warmer air to move to the upper part of the room, acompressor in the lower part of the cabinet and two separate passagewaysin the cabinet, extending from the compressor to the upper part of thecabinet, one passageway conducting air from the upper part of the roomto the compressor to cool the compressor, the other conducting airheated by the compressor to the upper part of the room above the pointwhere the air passes to the evaporator.
